With only three days left at Aunt Janet's house, I aimed to make the most of it. It was a beautiful sunny day, perfect for laying out. I walked along the deserted beach, the soft sand warm beneath my feet, looking for the ideal place to tan.
I glanced around as I reached a secluded spot to ensure no one was in sight. Satisfied that I was alone, a wave of excitement ripped through me. I've wanted to try sunbathing topless all summer but was always worried I would get caught. With so few days left of my vacation, I decided it was time to take the risk.
With a deep breath, I untied the straps of my bikini top and slipped it off. The cool breeze brushed against my bare skin, causing my nipples to harden.
I reached into my beach bag, pulled out a bottle of tanning oil, and poured a small amount into my palm.
Gently rubbing my hands together, I spread the warm oil across my skin, starting from my legs and working my way up. The fragrance of coconuts filled the air, heightening my senses and adding a touch of tropical bliss to the moment. The silky texture of the oil glided effortlessly over my body, leaving a subtle sheen in its wake.
I reached for a little more tanning oil to protect my exposed breasts. With a gentle touch, I applied the oil, allowing my hands to glide smoothly over the sensitive skin. I ran my slim fingers along the contours of my chest, tracing my fingertips along the undersides of my youthful tits. I savored the sensation, relishing the tingling that shot straight to my smooth pussy.
As I massaged the oil into my breasts, I couldn't help but admire how they responded, subtly glistening under the sunlight. My chest heaved with every breath, my pulse quickening with every tease of my fingers. I cupped my tits, pressing my greasy palms into my taut nipples.
I lost myself in the moment as I slowly trailed my slick fingers down my toned stomach to my beckoning pussy. I gingerly slid my hand beneath my barely-there bikini bottom, shocked to find how wet I was. Yet before I could begin to play with my wet cunt, I heard a familiar voice behind me.
"Someone is being a bit naughty," I heard Stan say from behind me.
My eyes shot open as I quickly pulled my fingers from my bikini bottom. I was shocked to find Stan and Carol standing beside me.
"Sorry, we didn't mean to interrupt. It looked like you were having a good time, honey," Carol interjected.
I blushed, embarrassed that I had just been caught masturbating in public.
"Oh, uh, sorry," I managed to respond, my cheeks flushed with arousal and embarrassment.
"Isn't she cute, honey?" Stan said to Carol, savoring the moment.
"Be nice, Stan," Carol jeered while kneeling in front of me, trailing her fingers gently across my shiny breasts.
My body shuttered at her sweet touch. Despite being in public, I looked at her longingly, begging for more.
"We are having a party tomorrow night. We hope you and Janet will be coming," Carol said before gently kissing me on my supple lips.
Taken aback, I quickly responded, "We have a guest staying with us. Can she come?"
"Any guest of yours is more than welcome," Stan declared, taking Carol's hand and continuing their walk down the beach.
I sat there breathless, watching them saunter along the beautiful coastline. For the next hour, I lay there thinking about how Mom would react to Carol and Stan.
I spent the rest of the afternoon taking in as much sun as my body could handle. I listened to the waves crashing into the shore while I wondered what kind of mischief Mom and Aunt Janet were up to back home. When the sun started to set, I headed back to Aunt Janet's house, hoping tonight would lead to some kinky fun.
"Stan and Carol say hi and that we should come to their party tomorrow night," I told Aunt Janet as I walked into the living room.
"Who are Stan and Carol?" Mom asked.
Aunt Janet chuckled softly, "I don't know if you are ready for Stan and Carol."
Mom huffed, "Oh, but my eighteen-year-old daughter is?"
"You have a point. Stan and Carol are a couple who own a beach house in town. They come every summer and throw weekly sex parties. From what they tell me, they are highly active in their swinger scene back home. Their parties here are a who's who of the hottest people in the area. It is invite-only, and it sounds like we got an invite," Aunt Janet explained.
"A sex party," Mom whispered, trying to process what she heard. "So, what happens at a sex party?"
I could tell the idea of going to a sex party with her daughter and sister was turning her on, especially now that we were all lovers.
"Well, it is a lot like a regular party, but instead of people waiting until after the party to fuck someone, they do it during the party, often in front of everyone else," I nonchalantly explained.
"You seem pretty knowledgeable about what happens at a sex party," Mom laughed nervously.
"I guess you have me to blame for that. We have been going to one every week since Britney got here," Aunt Janet explained.
Mom's jaw practically hit the floor. Fucking my Aunt was one thing, but her eighteen-year-old daughter frequenting sex parties seemed almost too much for her.
"I love them, Mom. It is so hot seeing all these people of varying ages so comfortable in their bodies and just fucking. I have learned so much from these parties. If you are lucky, I'll show you some of the tricks I picked up from Carol," I seductively said.
"And what kind of tricks would that be, young lady?" Mom joked.
I pulled Mom in for a passionate kiss. Mom's soft, plump lips nibbled and pulled at mine. I teased and traced Mom's lips with my tongue before suddenly pulling away.
"I guess you will have to wait and find out," I said, smacking her ass before heading upstairs to shower.
Mom looked shocked by my quick departure. She was clearly turned on by Aunt Janet and me talking about going to sex parties. I wanted the idea of going to an orgy tomorrow night to percolate in her brain while I washed the remaining tanning oil and sand off.
As the water cascaded down my body, my mind drifted to my first experience going to a sex party with Aunt Janet.
